Abstract

The invention relates to a method for charging the combustion unit of a coal-fuelled power station in which the coal is fed into said combustion unit at least partially using a stream of flue gas. According to prior art, said flue gas stream consists of the recycled flue gas of the coal-fuelled power station. The aim of the invention is to provide another stream of flue gas. To this end, the flue gas stream of a waste incineration plant is used as a flue gas stream, said flue gas stream having already been treated to large extent to remove mercury and other heavy metals, flue ash and hydrochloric acid.

Description

화력발전소 연소유니트 장전방법{METHOD FOR CHARGING THE COMBUSTION UNIT OF A COAL-FUELLED POWER STATION}METHOD FOR CHARGING THE COMBUSTION UNIT OF A COAL-FUELLED POWER STATION

J. Zelkowski 의 석탄연소, VEB 화력발전기술 유한회사(1986), 233 쪽 이하에서, 소위 분진연소장치의 경우 미세하게 분쇄된 석탄이 연기가스에 의해 화력발전소 연소장치 안으로 운반된다.In J. Zelkowski's Coal Combustion, VEB Thermal Power Technology Co., Ltd. (1986), p. 233, in the case of the so-called dust burner, finely ground coal is carried into the coal fired power plant by smoke gas.

이 경우, 연기가스로 화력발전소의 재순환 연기가스가 사용된다. 분진연소장치는 고상(solid bed) 연소장치에 비해 많은 장점이 있다.In this case, recycled smoke gas of a thermal power plant is used as the smoke gas. Dust burners have many advantages over solid bed burners.

DE 37 33 831 A1에 쓰레기와 같은 유기재료연소를 위해 석탄연소설비증기발생기와 조합하여 와류층 연소장치 작동이 알려져 있다. 이 경우 와류층연소장치의 연기가스는 증기발생기 연소영역으로 직접 유입된다. 석탄은 증기 발생기에 별도로 장입된다.In DE 37 33 831 A1 the operation of a vortex bed combustor is known in combination with a coal combustion plant steam generator for the combustion of organic materials such as waste. In this case, the smoke gas of the vortex bed combustion device flows directly into the steam generator combustion zone. Coal is charged separately to the steam generator.

DE 43 13 102 A1에 연소시킬 때 특히 폐기물을 소각할 때 방출되는를 제거하기 위해 연소가스량을 감소시키는 방법이 있다. 이 방법의 경우 연소배기가스와 공기분해로 얻어지는 산소로 이루어진 열분해용 합성연소공기가 사용된다.Emissions when burning on DE 43 13 102 A1, especially when burning wastes There is a method of reducing the amount of combustion gas to remove. In this method, a synthetic combustion air for pyrolysis composed of combustion exhaust gas and oxygen obtained by air decomposition is used.

본 발명은, 청구항 1의 상위 개념에 따른 화력발전소 연소유니트 장전방법에 관한 것이다.The present invention relates to a thermal power plant combustion unit loading method according to the higher concept of claim 1.

본 발명에 따른 실시예를 도에 나타냈으며 실시예에서 자세히 설명한다.An embodiment according to the present invention is shown in the drawings and described in detail in the examples.

도 1 : 본 발명의 실시예 흐름도1: Flowchart of an embodiment of the present invention

본 발명의 과제는 화력발전소 분진연소장치용으로 또 다른 연기가스를 사용하는 것이다.An object of the present invention is to use another smoke gas for the dust-burning apparatus of the thermal power plant.

이 과제는 청구항 1의 본 발명에 따른 조치를 통해 해결된다. 또 다른 청구항에 본 발명에 따른 방법의 선호되는 형태를 설명한다.This problem is solved through the measures according to the invention of claim 1. In another claim a preferred form of the method according to the invention is described.

본 발명에 따라 화력발전소 분진연소장치에 쓰레기 연소설비의 연기가스를 적어도 부분적으로 사용한다. 이 출원은 쓰레기 연소설비와 화력발전소가 공간적으로 인접해야한다는 것을 전제로 한다.According to the invention the smoke gas of a waste combustion plant is at least partly used in a dust-burning apparatus of a thermal power plant. This application is based on the premise that the waste combustion plant and the thermal power plant must be spatially adjacent.

쓰레기 연소설비의 연기가스는 본 발명에 따라 분진연소장치에 투입하기 이전에 문제가 되는 성분을 제거한다. 문제 성분은 비교적 작은 부피로 농축될 수 있다. 일반적으로 쓰레기 연소설비의 연기가스 흐름은 화력발전소의 연기가스 흐름보다 훨씬 작으므로 이러한 조치들을 사용하여 더 많은 연기가스 흐름에 분산되는 것을 방지할 수 있다.The smoke gas of the waste combustion plant removes problematic components prior to introduction into the dust combustion apparatus according to the present invention. The problem ingredient may be concentrated to a relatively small volume. In general, the smoke gas streams from waste-burning plants are much smaller than the smoke gas streams from thermal power plants, so these measures can be used to prevent the spread of more smoke gas streams.

문제 성분으로는 중금속, 특히 수은, 납, 카드뮴 및 염산을 들 수 있다. 비산재 역시 카드뮴과 수은이 포함되어 있으므로 본 발명에 따라 미리 분리한다.Problem components include heavy metals, in particular mercury, lead, cadmium and hydrochloric acid. Fly ash also contains cadmium and mercury, so it is separated in advance according to the invention.

특히 쓰레기 연소설비의 연기가스흐름은 연소설비용으로 사용하기 이전에 섬유필터와 염산세척기를 통해 유도된다. 섬유필터에서 비산재와 중금속, 특히 카드뮴, 납이 걸러진다. 염산세척기는 연화수소와 수은을 제거한다. 두 성분은 종래의 방법으로 제거된다. 특히 염소세척기의 세척액에서 연속적 또는 불연속적으로 수은을 분리할 것을 권장한다.In particular, smoke gas flows from waste-burning plants are introduced through fiber filters and hydrochloric acid washers before they are used for combustion plants. The filter filters out fly ash and heavy metals, especially cadmium and lead. Hydrochloric acid washers remove hydrogen and mercury. Both components are removed by conventional methods. In particular, it is recommended that mercury be removed continuously or discontinuously from the washing liquid of the chlorine cleaner.

본 발명은 일련의 장점을 가진다. 가장 중요한 장점은 쓰레기 소각설비의 경우 몇가지 배기가스세정성분을 사용하지 않아도 유해성분의 방출량이 증가하지 않는다.The present invention has a series of advantages. Most importantly, waste incineration plants do not increase the emissions of hazardous components without the use of some exhaust gas cleaning components.

쓰레기 소각설비의 연기가스는 화력발전소의 분진연소장치용으로 투입하기 이전에 질소산화물과 유황 산화물을 제거할 필요가 없으며, 따라서 쓰레기 소각설비에서 해당 가스성분을 얻을 수 있다. 질소산화물은 연소유니트 화염에서 환원되며, 유황산화물은 화력발전소의 연기가스세정설비에서 제거된다. 일반적으로 쓰레기 소각설비로부터 나오는 추가의 연기가스부피로 인해 화력발전소의 연기가스부피가 거의 증가하지 않으므로, 이 경우 별도의 조치가 필요하지 않다.The fume gas from the waste incineration plant does not need to remove nitrogen oxides and sulfur oxides before being put into the dust-burning unit of a coal-fired power plant, so that the gas component can be obtained from the waste incineration plant. Nitrogen oxides are reduced in the combustion unit flames, and sulfur oxides are removed from the smoke gas cleaning facilities of thermal power plants. In general, additional smoke gas volume from waste incineration plants rarely increases the smoke gas volume of thermal power plants, so no further action is necessary in this case.

또한 쓰레기 소각설비의 연기가스세정설비에 다중염소처리(poly chlorinated)된 탄화수소, 특히 디옥신과 퓨란의 분해 또는 흡착을 위한 구성요소를 설치할 필요가 없다. 본 발명에 따라 쓰레기 소각설비의 연기가스는 화력발전소의 연소유니트에 도달하며, 그곳에서 유해성분이 분해된다. 염화수소를 미리 분리하므로 화력발전소 연기가스의 염소는 많지 않기 때문에 연기가스에서 다중 염소 처리된 탄화수소가 다시 생성되지 않는다.In addition, there is no need to install components for the decomposition or adsorption of polychlorinated hydrocarbons, in particular dioxins and furans, in the smoke gas cleaning facilities of waste incineration plants. According to the present invention, the smoke gas of the waste incineration plant reaches the combustion unit of the thermal power plant, where harmful components are decomposed. Since the hydrogen chloride is separated in advance, there is not much chlorine in the thermal power plant flue gas, so the multi-chlorinated hydrocarbons are not produced again from the smoke gas.

또 다른 장점은 쓰레기 소각설비와 화력발전소가 공간적으로 근접해 있으므로 예컨대 전기 변압기와 같은 별도의 설비를 공동으로 사용할 수 있다.Another advantage is that the waste incineration plant and the thermal power plant are in close proximity so that separate installations such as electric transformers can be shared.

본 발명은 도를 통해 자세히 설명한다.The present invention will be described in detail with reference to the drawings.

쓰레기 소각설비 연기가스(1)는 섬유필터(2)로 유입된다. 이 경우 탄소를 첨가하지 않는다. 그 다음 연기가스는 염산세척기(3)를 통과한다. 이러한 방법으로 미리 세정된 연기가스는 별도의 처리를 하지 않고 화력발전소의 분진연소설비에 사용된다.The waste incineration plant smoke gas 1 flows into the fiber filter 2. In this case, no carbon is added. The smoke gas then passes through a hydrochloric acid cleaner (3). Smoke gas pre-cleaned in this way is used in dust-burning equipment of thermal power plants without any additional treatment.

염산세척기(3)의 세척수(4)는 적절한 장치(5), 예컨대 전해질 셀에 의해 수은이 제거된다. 그 다음 섬유필터에 걸러진 비산재 처리를 위한 산성 추출단계(6)가 이어진다. 고상-액상-분리(7)후에 고체소재가 압축(8)된 다음 연소된다.The washing water 4 of the hydrochloric acid cleaner 3 is de-mercured by a suitable device 5 such as an electrolyte cell. This is followed by an acidic extraction step 6 for the treatment of fly ash filtered through the fiber filter. After solid-liquid-separation (7), the solid material is compressed (8) and then burned.

액상으로부터 그 다음 처리단계(9)에서 중금속, 특히 카드뮴이 예컨대 전해질을 통해 제거되며 정화된 액체는 폐수로써 하수로로 배출된다.From the liquid phase the heavy metal, in particular cadmium, in the next treatment step 9 is removed, for example via an electrolyte, and the purified liquid is discharged to the sewer as waste water.
